Upgrading domain and forest from 2003 R2 V31 to 2008 R2 V47

We are going to adprep our domain to accept 2008 DC's

We currently have 4 DC's all running Windows Server 2003 Standard R2 SP2

The schema Version is 31

I am preparing to do the following using the 2008 (x64)  R2 SP1 DVD
On DC holding all the FSMO roles

d:\support\adprep\adprep32 /forestprep

then

d:\support\adprep\adprep32 /domainprep /gpprep

Can anyone confirm this is the correct procedure.

We have a pretty simple domain. We are also running 2003 Exchange.

Any other things to be concerned about or considerations?

Hi, if you wish, you may follow an article on my blog for that at
http://kpytko.wordpress.com/2011/08/25/adding-first-windows-server-2008-r2-domain-controller-within-windows-2003-network/

after that, you may wish to transfer FSMO roles to the new DC

when you transfer PDC Emulator role to the new DC then you need to advertise new time server in your forest/domain
[...]- after transfer of the PDCEmulator role, configure the NEW PDCEmulator to an external timesource and reconfigure the old PDCEmulator to use the domainhierarchie now. Therefore run on the NEW "w32tm /config /manualpeerlist:PEERS /syncfromflags:manual /reliable:yes /update" where PEERS will be filled with the ip address or server(time.windows.com) and on the OLD one run "w32tm /config /syncfromflags:domhier /reliable:no /update" and stop/start the time service on the old one. All commands run in an elevated command prompt without the quotes. [...]

it's an extract from MVP blog at
http://msmvps.com/blogs/mweber/archive/2010/02/10/upgrading-an-active-directory-domain-from-windows-server-2003-to-windows-server-2008-or-windows-server-2008-r2.aspx

and as the final step, you may wish to demote the old DC(s)
